2N2904AL and 2N2905AL
PNP SWITCHING SILICON
TRANSISTOR
Qualified per MIL-PRF-19500/290
DESCRIPTION
This family of 2N2904AL and 2N2905AL switching transistors are military qualified up to the
JANS level for high-reliability applications. These devices are also available in a TO-39
package. Microsemi also offers numerous other transistor products to meet higher and lower
power ratings with various switching speed requirements in both through-hole and surface-
mount packages.
